James Hardie Fence Installation: The Woodland Hills Owner’s Guide
A James Hardie fence installation in Woodland Hills typically runs between $3,500 and $9,000, and the job usually takes two to four days depending on the linear footage, soil conditions, and whether we’re pulling an old fence or starting fresh. Most homeowners call us after a section blows out during a Santa Ana wind event, or when they notice the bottom rails have started to crumble from sprinkler overspray and Woodland Hills’ alkaline clay soil sitting against the fiber cement. You’re not just replacing boards, you’re fixing the system that holds them: posts, rails, fasteners, and the spacing that keeps Hardie’s fiber cement from cracking under our heat-and-cold swings.
Which James Hardie Models This Applies To
We’re talking about James Hardie’s fiber cement fence panels and trim boards, not their siding line. The key spec that trips people up is thickness: Hardie’s fence material runs 5/16 inch, which is thinner than the 7/16 inch siding planks, so you can’t just grab siding stock at the yard and expect it to hang the same way. Fasteners matter more here than they do on wood. Fiber cement has almost no give, so if the post spacing is off by more than half an inch, the panel binds and eventually cracks at the fastener line. When we quote a job, we verify the existing post spacing before ordering anything. James Hardie doesn’t make a complete pre-assembled fence system the way some vinyl manufacturers do; it’s a board-and-trim product that gets installed against a properly built post-and-rail frame. For aftermarket equivalent boards, we’ve seen quality options from Allura and Nichiha that hold up fine in Woodland Hills, but they don’t match Hardie’s color or texture perfectly. If you’re replacing a few sections on a fence you want to keep uniform, we recommend staying with genuine Hardie stock so the repaired sections don’t read as patches.

Signs Your James Hardie Fence Installation Is Failing
- Cracks radiating from screw heads. This is the number one failure we see in Woodland Hills. The installer over-torqued the fasteners or didn’t pre-drill, and the board has been under tension since day one. Once a crack starts, it follows the fiber cement grain and the panel needs replacing.
- Bottom edge crumbling or flaking. Fiber cement wicks water from direct ground contact or constant sprinkler hits. In Woodland Hills, where lots slope and irrigation runs year-round, we see this on fences that were set too close to grade. The fix is pulling the affected boards, trimming them up, and resetting the reveal height.
- Posts leaning or shifting at the base. The boards are rarely the problem when a fence starts to lean. Woodland Hills has expansive clay that moves with the seasons, and a post set in concrete that wasn’t deep enough will walk. We dig new post holes to 24 to 30 inches and use proper drainage gravel so the post doesn’t sit in a bowl of water.
- Gaps opening at board seams. Fiber cement expands and contracts with temperature swings, and Woodland Hills gets real swings: 40-degree winter mornings to 110-degree summer afternoons. If the original installer butted boards tight with no expansion gap, the seams push apart or bow.
- Chalky white residue running down boards. That’s efflorescence, a sign of trapped moisture working through the material. It’s cosmetic at first, but it means water is getting where it shouldn’t be. Left alone, the boards swell and delaminate; we find this a lot on fences under heavy tree cover in the canyons off Topanga Canyon Boulevard.

AfterReplacement Cost & What’s Included
For a full James Hardie fence installation in Woodland Hills, plan on $3,500 to $9,000 installed. Most jobs land in the middle of that range. Here’s what drives the number: linear footage is the obvious one, but the bigger variables are post condition and access. If the existing posts are solid and we can reuse the frame, you’re replacing boards and hardware and the price drops to the low end. If we’re sinking new posts into hillside clay or cutting through roots, labor climbs. If the old fence has to be hauled off, disposal fees add $300 to $600. Every quote we give is a written line-item price before we start: boards, rails, fasteners, post work, haul-away, the whole thing. The number you approve is the number on the invoice. No change orders because we found a surprise halfway down the line. And the work carries our 365-Day Done Right Promise: if it’s not right, we make it right, in writing.
DIY or Call Us?
You can safely check the post spacing, measure the board length, and confirm whether you’re looking at genuine Hardie or an aftermarket board. You can even pop a loose board and look at the fastener pattern. What goes wrong with DIY fiber cement work is the handling. A 5/16-inch fiber cement panel is brittle until it’s fastened; lift it wrong or let it hang unsupported and it snaps. Cutting it without proper dust control sends silica into the air, and that’s not a health risk worth taking in a backyard where kids play. The good news: our crews carry James Hardie-compatible boards, stainless fasteners, and the right trim profiles on the truck, so we can usually do the whole swap in one visit. If you’re in Woodland Hills and want a price before you decide, call (341) 217-2776 and we’ll come measure it.
FAQs
A properly installed James Hardie fiber cement fence lasts 20 to 30 years in Woodland Hills, though the hardware sometimes needs replacing before the boards do. The real lifespan killer here is ground contact and constant irrigation; keep the bottom edge off the soil and the boards will outlast any wood fence on your street. Call (341) 217-2776 if you want us to look at the specific fence you have.
No, a cracked fiber cement panel can’t be structurally repaired; the crack will keep running. What you can do is replace the single panel and reuse the frame if it’s still sound, which keeps the cost at the low end of the range. We’ll tell you honestly whether the damage is isolated or a sign the whole fence was installed wrong.
Most Woodland Hills installations take two to four days, with a day of that for post setting and concrete curing if we’re rebuilding the frame. Board replacement on an existing frame can be done same-day if we have your measurements. Give us a call at (341) 217-2776 and we’ll give you a timeline with the estimate.
We keep common James Hardie fence board sizes and trim profiles on our trucks for Woodland Hills jobs, and we can usually source specialty colors or textures through our supplier network within a few days. If you want an exact match, send us a photo of the existing fence and we’ll confirm the stock before we show up.
